滑轮组合牵引系统快速安装T型球墨铸铁管施工技术的应用

Application of Construction Technology of Quick Installation of T-type Nodular Cast Iron Pipe with Combined Pulley Traction System

该文介绍了利用滑轮组合牵引系统快速安装T型球墨铸铁管的施工技术。通过若干定、动滑轮组合构成的牵引系统,将竖向机械牵引力转换成管道轴向的均匀牵引力,实现了由机械牵引代替人工牵引的转变。该技术拥有“效率高、成本低,操作性强”的特点,具有一定的推广价值。

This paper introduced the construction technology of quickly installing T-type nodular cast iron pipe with the combined pulley traction system. Through a traction system composed of a combination of fixed and movable pulleys, the vertical mechanical traction force is converted into a uniform traction force in the axial direction of the pipeline, thereby realizing the transformation of mechanical traction from manual traction. The technology has the characteristics of "high efficiency, low cost and excellent operability", so it has certain promotion value.
